To all whom it may concern Be it known that we, JAMES IV. Brass and Ham HATCH, citizens of the United States, and residents of Mercer, in the county of Mercer and State of Pennsylvania,

have invented certain new and useful Improvements in Fire-Extinguishers, of'which the following is a specification.

The main Object of our invention is to provide means for enriching the solution operation is nearly ineffective for the reason that only the solution is being discharged and not the gas, the latter being the fire extinguishing agent and not the former, and the operation is thus rendered effective for only the last stages of discharge.

It was in order to overcome this loss of veiiiciency that our invention was conceived, and we accomplish our result by enriching the solution from the beginning of discharge and thus utilize the entire period of discharge effectively.

Our invention is fully described in the following specification, of which the accompanying drawing forms a part, said drawing representing a hand fire extinguisher, inverted, provided with our invention, and partly in section to show structural details.

In the drawing forming a part of this application we have shown a tank or container 1 of the usual or any desired form for the solution 2 and the agents, not shown, which are brought into contact upon inverting the container to produce, for instance, carbonic acid gas for forcing the solutlon out of the tank through a flexible hose 4 to the point of use, the space for the said gas being indicated at 3 after the container has been inverted, all of this being of any desired formation.

In the practice of our invention we provide a tube 5 extending from the tank discharge port 6, where it is supported by a spider 7 or the like, to a point slightly removed from the bottom 8 of the tank, said tube being perforated at its end adjacent the tank bottom 8 and being open to the i Specification of Letters Patent. Patented June 13, 1916,

Application filed January 5, 1916. Serial No. 70,447. i I I l i hose 4, a goose-neck9being provided for the hose 4 at the port 6, and'we also provide a brace or support 10 for the tube 5 of any desired form.

The gas producing agents, in the present form of tank, are carried in a removable head 11 which normally is at the top of the tank but, when the tank is inverted to bring said head to the bottom thereof, the gas is produced and entersthe space 3 above the solution 2 and forces said solution through the hose 4; whence it is directed to the flames.

The perforated end of the tube 5 is always above the solution level when the extinguisher isin action, thereby allowing the generated gas in the space 3 to pass through the tube'5 to the port 6 and thoroughly mix with and enrich the solution on its way to the hose 4, thus causing the action of the gas laden stream to be as effective at the beginning of operation as near the end thereof. A further effect is that by releasing the gas as it generates in the space 3 this relief allows more gas to generate than would otherwise be possible. In the present extinguishers the gas generated and not liberated becomes soluble and again enters the solution and decomposes, thus causing a loss of generated gas, also retarding the chemical action of the solution, and impairing its total efficiency.

We find that by liberating this gas and utilizing it to enrich the discharge and render the same more effective we do not lessen'the pressure on discharge of stream but, instead, stimulate the same so that in actual tests the period of discharge has been materially lengthened.

Our invention can be applied to either hand or truck extinguishers of any size or capacity, in different styles, and to meet dif ferent conditions, and we do not, therefore,

limit ourselves to the exact structural de-v 2. The combination With a fire exnames to this specification in the presence tinguisher tank of the reversible type, havof tWo subscribing Witnesses. ing a discharge port, of a tube in said tank open at each end and extending above the JAMES W. BYERS. level of the solution in either position of the HART HATCH. tank, one end of said tube being in proXim- WVitnesses: ity to said discharge port. THOS. MGCLAIN, Jr. In testimony whereof We have signed our RUSSELL LYTLE.
